Imishini Yokwelapha Amanzi Angcolile Yokudaya
Ukwelashwa ngokomzimba
Le ndlela iwukuxuba impuphu noma izinhlayiya zezinto ezinezimbobo ezifana ne-activated carbon kanye nobumba kanye nendle, noma ukuvumela indle idlule embhedeni wokuhlunga owakhiwe yizinhlayiya zayo, ukuze ukungcola okusendle kufakwe phezu kwezinto ezinezimbobo noma kuhlungwe.
Kunezinhlobo eziningi zama-adsorbent asetshenziswa ekwelapheni i-adsorption, futhi ukukhetha kwama-adsorbent kumadayi kufanele kucatshangelwe kuphrojekthi, futhi ama-adsorbent kufanele akhethwe ngokuya ngekhwalithi yendle. Imiphumela ikhombisa ukuthi ekudayiseni amanzi amdaka nge-pH=12, izinga lokususwa kwedayi ye-anion lingafinyelela ku-95%-100% ngokusebenzisa ama-silicon polymers (i-methyl oxygen) njenge-adsorbent. I-Kaolin nayo iyi-adsorbent. Izifundo zikhombisile ukuthi i-kaolin ingamunca ngempumelelo amadayi aphuzi aqondile emanzini amdaka ngokwelashwa kwe-cation ende ye-organic chain.
Ukwelashwa ngamakhemikhali
Ihlukaniswe kakhulu ngezinhlobo ezimbili zendlela yokujiya kanye nendlela yokujiya, ezinemiphumela yazo ekwelashweni kwamanzi.
Indlela yokuhlanganisa ihlanganisa kakhulu indlela yokuhlanganisa imvula kanye nendlela yokuhlanganisa igesi. Iningi lama-coagulant asetshenziswayo ikakhulukazi usawoti we-aluminium noma usawoti wensimbi, phakathi kwawo i-aluminium chloride (PAC) eyisisekelo inokusebenza okungcono kokufaka i-bridge, kanti i-ferrous sulfate inentengo ephansi kakhulu. Izinzuzo eziyinhloko zendlela yokuhlanganisa i-cluster ukugeleza kwenqubo okulula, ukusebenza okulula nokuphathwa, ukutshalwa kwezimali okuncane emishinini, indawo encane kanye nokusebenza kahle kokususa umbala kumadayi angenawo umoya. Okubi izindleko zokusebenza eziphezulu, udaka olukhulu kanye nokuphelelwa amanzi okunzima, kanye nomphumela omubi wokwelashwa kwamadayi angenawo umoya.
Kunezindlela eziningana zokudaya, njengokudaya i-ozone kanye nokudaya ukukhanya. Indlela yokudaya i-ozone ingathola umphumela omuhle wokususa umbala kumadayi amaningi, kodwa umphumela omubi wokususa umbala kwi-sulfur, ukunciphisa, upende kanye nezinye izidayi ezinganyibiliki. Ukwelashwa nge-photooxidation kokudaya amanzi amdaka ukusebenza kahle kokususa umbala kuphezulu, kodwa ukutshalwa kwezimali kwemishini kanye nokusetshenziswa kwamandla kudingeka kuncishiswe kakhulu, ukusetshenziswa kwale ndlela ekhaya akuwona amabhizinisi amaningi.
Ukwelashwa nge-electrolytic
I-Electrolysis inethonya elihle ekwelapheni amanzi amdaka anombala oqukethe i-asidi, izinga lokushintsha umbala lingu-50% ~ 70%, kodwa umphumela wokwelashwa emanzini amdaka anombala ojulile kanye ne-COD ephezulu awulungile.
Kuyaqondakala ukuthi izibalo, zonke izinhlobo zamadayi ngenxa yezakhiwo ezahlukene ze-electrochemical ekwelashweni kwe-electrolytic kwesilinganiso sabo sokususwa kwe-COD zinomehluko omkhulu, ukuhleleka kwesilinganiso sokususwa kwe-COD ngokuvamile: amadayi e-sulfide, amadayi e-VAT dye-acid, amadayi asabelayo e-dye-neutral, amadayi e-direct dye-cationic.
